There are estimates the world's militaries contribute 5.5% of greenhouse gasses, nvm all the destruction and emissions needed to rebuild it all again.

And all that time and money wasted on killing each other could be used to make live a whole lot more comfortable. With the latest Ukraine and Gaza war, 2.44 trillion spend on wars in 2023. Nuclear Fusion total investment stands at 7.1 Billion, 0.3% of military spending in 2023.

We can't kill the Earth (yet) but we've become very efficient in killing each other :(

Well, one of the best ways to reduce co2 emissions if that is ones goal is to kill people. 

And a good way to kill people is to increase CO₂ emissions

In earths history there are episodes of rapid increase of CO₂ followed by a dropoff. It surely killed some species on the way.
